To all wizom it may concern:

Be it known that I, FRANK HOWARD, a

citizen of the United States, residing at Potter, in the county'of Lawrence and State of Kentucky, have invented IlGWand useful Improvements in vaporizing Devices, of-

which the following is aspecification.

.Thieinvention resides in the provision of with a combustion engine and embodies means for initially heating and vaporizing the fuel to start'the motor subsequent to which the fuel is conveyed from its source to a-heating chambersurrounding the enhaust manifold, wherein it is properly heated and 1 vaporized and then introduced through a valved communication into the intake manifold. f r

p More specifically stated, the means above referred to for initially heating the fuel for the starting of the motor, is in. the formof a burner having fiues and oil chambers sur- I rounding the flues theohambers being of n such cross sectional configuration to provide maximum heatlngsurfaces, so that the fuel} entering the: chambers will be properly heated and vaporized in quicko'rd'e'r. i

Ii -carrying out the invention, I provide means for supplying the fuel tank with air under pressure from the motor; the means including a safety valve" so that the pressure in the tank is maintainedat a more or less constant'degreeL--"- a I The nature and advantages offthe' invention'willbe betterunderstood when the fol-' lowing detail description'is taken in connection with the accompanying drawhigsythe invention residing in; the construction, comclaimed. y I

I The vaporizer forming the subject matter. f y of my invention comprises a-"he ati'ng 'cha1n-'"' ber Y 14 which surrounds the ei rhaustfniani amount-of fuel admittedintof 'the ='he'a tincr chamber 14'; 'lheybranch 18" is also provid with; a U-shap'ed' pipe 22fterminally eonnected Withsa'idbranc 18' at; opposite sides of the valve-2l,fwhile the U -shaped"pip'.'-is,-- equippedwith a checkvalve23il Tll lS f COlIA struction obviously-provides "for theire'turni f ,fuelfromth'e chambe 14 1 h :brnchl 1 l8 and supply pipe l9ii1cijdent'to expan ion; in' the heating chamber 14. s

For the purpose of initially team-gland at B and inclu'ded in the conne tion between fold-10; The heating device isin the nature" i Y and 28 respectively, more cle'arlyillustrated plied with fuel fromthetankflZ "through" has communicatio This chamber is in communication "with the wickc'hainber 2 k the level'of the fuel withinthe-wick'chain!" ber'2t. The fue1' from thetank';17 is 011; veyedto the heating chambers 27' and 28 re pipe'3l leading from the. mainsupply pip v spectivel'y ofthe'bu'rner through afbr aii ftfYJ together in a dome atthe top i'this domebe.

ing indicated at 32, and from which leads the discharge pipe 33 for conveying the fuel from the dome 82 into the intake manifold 10. This communication is controlled by means of a valve 84. As shown in Figure 2, each "of the heating chambers is defined by the space between the inner and outer shells 35 and 36 respectively, the inner shell 35 forming part of the heating chamber 27 is used as a flue 37, while the space between the outer shell 36 and the inner shell 35' of the chamber 28 defines another flue indicated at 38. To maximize the heating surface of the respective heating chambers the inner wall 35 of the chamber 28 and the outer wall 36 of'the chamber 27 are corrugated as indicated at 39. The corrugations of the two mentioned shells of the re spective burners extending toward each other and are disposed in staggered relation within the flue 3 8 as clearly illustrated in Figure 2.

Arranged adjacent theseat 3 is a hand iactuated pump 40 for supplying the tank 17 with air through the pipes di and 12. The pipe 42 communicates with the tank 17 at, one end, and with the space between the doublediaphragm 43. The double diaphragms form part of a regulator interposed between one cylinder of the motor A and the pipe 42, so that air may beconveyed from the motor through the pipe 42 to the tank 17, in counter-distinction to the use of .,,the hand pumpv 44: for this purpose. The

regulator maintains the air pressure within he fuel ankat a constant degree. Associated with the cylinder IDQIlhlOIlQ-Cl 1s a coupling 45 which establishes a communication between the cylinder of the motor-and an air line 46 which. leads from the core plinp; 45 to the space between the double diaphragm 4:3. The air line 46 includes a check valve 47 and an air; strainer 48. In

' practice,-the air is forced fromthe cylinder of the motor to, the air line'lo into the a space, between the double diaphragm i3,

to the tank 1'7.

the latter being provided to prevent interruptions in the flow of air from the motor from the space between the double dia-' phragm which as above stated forms part of a regulator, through the pipe 42 to the tank 17, maintaining the pressure in the tank at ';& constant degree. lNl-ounted upon the dash board 12 is a gauge to communicatingwith the pipe 42 by means of an extension 50. The gauge is equipped with a safety valve 5i of any suitable construction and by use of which the pressure inthe tank 17 is maintain-ed amore or less constant degree.

Inpr-actice, the burner B is first lighted and the valve 52 opened to allow the fuel fromthe tank 1'1 to pass through the pipe 19 into the heating chambers 27 and 28 respectively of the burner and to also pass Obviously the air passes through the chamber 29 into the wick chamber 2 l. The fuel in the chambers 27 and 28 is properiy heated and vaporized therein and conveyed through the pipe 33 into the intake manifold l0. After the motor has been started the burner B is extinguished and the valve closed. The fuel from the tank 17 is then conveyed to the supply pipe 19 and the branch pipe 18 into the heating chamber l l which surrounds the exhaust manifold ll. Obviously the fuel admitted to the heating chamber 14:, is heated andvaporiaed from the heat of the exhaust, and is conveyed from the chamber M to the intake manifold through the valve connections 15 and 16. The valve 21 may be fully opened to admit a predetermined quantity of fuel from the tank 17 into the heating chamber lat and then closed, or it may be opened to any desired degree depending uponthe particular quantity of fuel to be, admitted to. the heating chamber 14. In other words. the valve 21 may be maintained use, andproperly adjusted to regulate the quantity of fuel admitted to the chamber M. The return of fuel from the chamber 1% incident to the expansion of the chamber or tor any other reason, is allowed to pass through the pipe 22 and check valve 23 intO.

the air line 4E6, the check valve 47 and air strainer 4:8 into the space betweenthe double diaphragms 48, fromswhere it is conveyed to the pipe 42 into the tank 17 As above stated, a safety valve is included in this connection so as to maintain the pressure withopen at all times, while the machine is in l in the tank at a more or less constant degree. I

In Figure 4;, I have disclosed a modified form of an exhaust manifold. In this instance, the exhaust manifold is indicated at 56 and is corrugated or fluted, the corrugas tions 57 being longitudinally disposed and projecting within the manifold as shownfi The manifold is surrounded by a heating chamber 58 and by reason of the construction illustrated it is obvious that a maximum heating surface for the fuel is provided. In other words, the fuel is not only heated in the space between the manifold and the heating chamber the wall of which is indicated at 58, but enters the corrugations 57 which by reason of their disposition within the manifold are subjected to the greatest heat intensity of the exhaust. Y

pipe 61 having its terminals communicating with the heating chamber as shown at 62. By reason of this construction the fuel is not only heated in the space between the exhaust manifold 59 and the chamber including a wall 60 but a portion of the fuel flows.

in one end of the coil pipe 61 and out the opposite end thereof, and being returned to the chamber including the wall 60. Consequently the fuel is not only heated to a high temperature but also heated in quick order. For this purpose, it is necessary that the terminals 62 of the coil pipe be submerged or in other words disposed beneath the level of the fuel in the chamber embodying the wall 60.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to the details herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thusdescribedmy invention What I claim as new is f r 1. A vaporizer of'the character described comprising a wick chamber, a float chamber arranged to one side of and communicating with the wick chamber, a float valve controlling said communication, spaced concentrically "disposed heating chambers,'a supply pipe communicating with both the said float chamber and the said heating chambers, a dome common to both of said heating chamc bers, and-an outlet pipe leading from said dome. m

2. A vaporizing device of the character described comprising a wick chamber, afloat chamber arranged to one side of and communicating vwith the wick chamber, a pluvrality of spaced concentrically disposed shells defining-Ya plurality "of heating chambers, a supply pipe communicating with the wick chamber, and with said heating chambers, the said shells being radially corrugated in a longitudinal" direction, with the corrugations of the respective shells extending toward each other and disposed in staggered relation, .a dome common to said heating chambers, and an outlet pipelead fromsaid-dome.
